[xep-support] [xep] [XEPJ002E][ERROR] Element 'fo:external-graphic' must be empty.

I get the above error using DITA content transformed to PDF through Oxygen 17 and DITA toolkit version 2.1 with XEP 4.24 on a Windows 7 system. This message appears to show up for each image element that has an embedded alt element, like this:

      <image height="89px" width="165px" href="logo.png" >
                <alt>Company name</alt>

Some older, similar content that uses the deprecated alt attribute rather than the alt element processes through XEP without showing this error.

XEP appears to fail after hitting 12 image elements with embedded alt elements, showing a message like this:

[xep] Rendering failed: Invalid XSL FO source 'file:/c:/buildtemp/topic.fo': 12 errors found during validation

Oxygen's transformation completes successfully, but produces a zero-byte PDF, whether XEP hits one of these errors or 12.

The image code in stage1.xml and stage1a.xml looks like this:

            <image class="- topic/image " height="89px" href="logo.png" placement="inline" width="165px" xtrc="image:1;18:65" xtrf="file:/C:/Temp/test.xml">
                <alt class="- topic/alt " xtrc="alt:1;19:22" xtrf="file:/C:/Temp/test.xml">Company name</alt>

In stage2.fo, stage3.fo, and topic.fo it looks like this:

            <fo:inline><fo:external-graphic content-height="89px" content-width="165px" src="url('file:/C:/Temp/logo.png')">


What do we need to do to get our setup to handle image elements with alt elements?

Thank you for any help.
